Application filed June 12, 19.09, Serial No.

To all whom it may concern:

. Be it known' that I, CHARLES A. LIND s'rRoM, a citizen ofthe United States, residing at Pittsburgh, Northside, in the county of Allegheny and State of Pennsylvania, -hav'e inven ted certain new and useful Improvements in Tank-Cars, of which the following is a specification.

' An object of the present invention is' to provide an improved tank car construction of'the form in which the tank is securely fastened tothe underframe, preferably. substantially at the center of the car and sup ported at or near its ends in such a manner that, expansion and contraction of the metal the tank, due to temperature changes,

' may? take place.

v construction.

A; specific object of the present invention is-to provide a tank car construction of the above described type, in which while the tank is securely fastened to the unclerframe it may from.

For producing these results, suitable means is employed for bolting the tank to the underframe to hold the same securely to the underframe and in such a manner as to prevent any relative movement between the tank and underframe, except that due to expansion and contraction of the metal.

The invention is fully, clearly and accurately described in this specification, and is shown in the accompanying drawings in which like reference characters refer to like parts, and in which 4 Figure 1 is an elevation of a tank car, minus its trucks, equipped with an embodiment of the invention; Fig. 2 is a plan view of the subject-matter of the invention,

showing a portion of the bottom sheet of the tank; Fig. 3 is a longitudinal section of the same on the line 3 3 Fig. 2; Fig. 4 is a transverse section of the same on the line 1-4, Fig. 2, and Fig. 5 is a like view on the line 55, Fig. 2.

Referring now in detail to the drawings, 1 represents the center sills and 2 the saddles or cradles which, together with the center sills 1, constitute substantially the entire underframe of the car; the underframe of the car, however, may be of any suitable As shown in the drawings, there are two center sills 1 spaced apart by cover plates 3, and they form the backbone of the car, adapted to receive and transmit specification of Letters Patent.

bufiing and pulling shocks. 4 is a tank resting on the saddles or cradles 2 at or near its ends but not permanently secured there to. Any suitable number of tankstays or bands 5 may be employed for holding the tank to the-underframe. These stays or hands 5 may also be located in any suitable position relative to the length of the car.- As a part of the means for securely and detachably holding the tank to its underframe and preventing relative longitudinal movement between the tank and its underframe, an anchor plate, casting or member 6 is employed which is securely attached, as by rivets, to the tank l, preferably on the underside at its longitudinal] and transverse center. The anchor casting or memher 6 is provided with a concave upper face and a pair of depending legsor projections 6 spaced from each other in a direction longitudinal of the car, and these legs or projections 6 and the whole anchor casting or-member 6 may be and preferably are ribbed and reinforced to render the same strong enough to resist the shocks to which they are subjected.

Cooperating with the anchor plate, cast ing or membe 6, to hold the tank securely to its underf'ame, is employed an anchor plate, casting or member 7, preferably of sills 1, where it will be between the depending legs 6 of the plate, casting or member 6, when the parts are in adjusted positions.

Finally, plates, members or castings 6 and 7 are secured to each other through the medium of bolts 8 passing through suitable perforations in said members 6 and 7 and in butt plates 9 located a suitable distance and spaced from plates 7 and riveted or otherwise suitably secured to the center sills 1.

Plates 7 and 9 preferably extend between and are secured toeach of the center sills 1 so that they form struts or stiffeners for the center sill at the point of attachment of the tank 4 to the underframe. These plates are provided with vertical. sides and ends and also horizontal portions, but one or more sides of each are preferably left open so that manipulation of the bolts and rivets forming parts of the connection is facililongitudinally of the car. If desired, how

tated'. The length of the plate 7 is made as nearly as possible the same as the distance between the opposing faces of the legs 6*, as the use of rough castings will permit, to obtain as snug a fit and prevent as far as possible any relative movement of the parts ever, the opposing. faces of the plates 7 and the legs 6 may be milled to obtain an absolutely snug fit. Cotters 8 are illustrated in the drawing for the purpose of holding the bolts 8 in adjusted position, but' bolts 8 may, if desired, be threaded in the customary manner and nuts may be employed. The horizontal side or web of the plate 7 is shown perforated at 7 through which perforation the tank nozzle 10 extends. Of course, the

nozzle 10 may be locate in any other con venient position on the tank 4, but the customary location at center of botom of the tank is desirable since the perforation 7 will then occupy a space in the neutral axis of the upper side or web in the plate 7.

The plate 7 is not only designed to stiffen the center sill construction of the car, but is also designed for the purpose of proper transmittal of the strains of bufling and pulling shocks, and for the proper distribution ofstress within plate 7. The plate 6 is also perforated at its neutral axis for the same purpose and for the same reason as stated in connection with the perforation 7* of the plate 7. Nozzle 10 is provided with an annular flange by means of which it is riveted or otherwise secured to tank 4, such flange being riveted to the undersurface of plate 6, as a better and easier fit of the nozzle is possible than if said flange were located beneath plate 6. Locating the perforation in the plate 6 and the nozzle 10 centrally on the plate 6 makes the rivets more accessible to the riveting tools, as the riveting in this position is not interfered with by reinforcing flanges or vertical faces of plate 6.

The construction thus shown and described provides a securing means for the tank on the underframe which leaves the tank on either side of its longitudinal center absolutely free for expansion or contraction due to temperature changes and provides againstlongitudinal, vertical or pivotal movement of the tank on its underframe.

The specific connection between the tank and underframe shown and described may, however, be located at any other suitable point longitudinally of the car and may be duplicated. For instance, a like connection may be located at each bolster point but.

would not be quite as advantageous as the expansion and contraction of metal in the tank wouldt-hen be limited to a greater. or less extent unless longitudinal movement between the parts was provided for.

By arranging the anchor plates 6 and 7,

so'that when the parts are in adjusted positions they are located between the center sills 1, it will be seen that the center of gravity in the tank is lowered over what it would be if the connection between said anchor plates was made at a point above the center sills.

Having thus described my invention, 'the located below the upper horizontal plane of the underframe, one of said members embracing the other of saidmembers and a bolt securing said members to each other. I
